Prof Abdon Antangana
Prof Abdon Atangana, a Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS) and South Africa’s top-ranked scientist in Mathematics, wants to prepare the next generation of African professors.

A new book written by Prof Abdon Atangana, Professor of Applied Mathematics at the Institute for Groundwater Studies at the University of the Free State (UFS), in collaboration with one of his students, on the flow of groundwater, suggests several new and modified models to better predict anomalous behaviours of the flow and the movement of pollution within complex geological formations.

Mathematical Analysis of Groundwater Flow Models is one of two books Prof Atangana published recently that he wrote with his students. The other, Fractional Stochastic Differential Equations: Applications to Covid-19 Modeling, provides a thorough conversation on the underpinnings of COVID-19 spread modelling. He wrote the book with a postdoctoral fellow, Dr Seda Araz Igret from SIIRT University, Turkey. Since 2016 he has published a total number of six books, some of which are still under evaluation by Springer and Elsevier.

Time to prepare next generation of African professors 

This highly cited researcher is excited about collaborating with his students on projects such as these as he feels it is time for him to prepare the way for the next generation of African professors. Prof Atangana is ranked at No 219 in the world rankings and No 1 in South Africa by Research.com, a leading academic platform for researchers. 

According to the platform, which recently released the 2022 Edition of its Ranking of Top 1000 Scientists in the field of Mathematics, the ranking is based on the H-index metric provided by Microsoft Academic and includes only leading scientists with an H-index of at least 30 for academic publications in the field of Mathematics.

“Both books are important for me because they are first-time published books with my own students. There is a time to prepare the way for yourself and a time to prepare ways for the next generation. It is time for me to prepare the way for the next generation of African professors. I wish that the next time this list (https://research.com/scientists-rankings/mathematics/za) [is released] many of my students [will] appear,” says Prof Atangana.

About his book with Dr Igret, he says it presents the dynamic of COVID-19 spread behaviour worldwide. It is noticed that the spread dynamic followed process with nonlocal behaviours, which resemble power law, fading memory, crossover, and stochastic behaviours. Fractional stochastic differential equations are therefore used to model spread behaviours in different parts of the world. 

“The content coverage includes a brief history of COVID-19 spread worldwide from December 2019 to September 2021, followed by statistical analysis of collected data for infected, death and recovery classes,” says Prof Atangana.

Mathematical analysis of Groundwater Flow Models serves as a valuable resource for graduate and PhD students as well as researchers working within the field of groundwater modelling, says Prof Atangana. It includes features such as:
• Modified numerical and analytical methods for solving new and modified models for groundwater flow and transport 
• New flow and transform models for groundwater transport in complex geological formations 
• Examination of fractal and crossover behaviours and their mathematical formulations

Top-ranking scientist 

Prof Atangana was also recently elected as a fellow of The World Academy of Sciences (TWAS) and received the World Academy of Sciences Award for Mathematics (TWAS -Mohammad A Hamdan, 2020) on 1 November 2021.

Very recently, he was also ranked No 1 in the world in Mathematics, No 186 in the world in all the fields, and No 1 in Africa in all the fields, according to the Stanford list of 2% single-year table.

He was also named among the top 1% of scientists on the global Clarivate Web of Science list. Fewer than 6 200 or 0.1% of the world’s researchers were included on this list in 2019, 2020 and 2021, with fewer than 10 of the scientists hailing from South Africa. 

“While my name is ranked No 1 in South Africa and No 219 in the world, this shows the impact of my research that has been done since 2013. It is worth noting that this ranking disadvantages younger researchers. For example, I got my first publication in 2013 but the researcher who was ranked No 1 started in 1972. To make the ranking fair, the total H-index should be divided by the number of years of publication. I am very proud to see that despite this disadvantage I am still topping in South Africa and am No 219 in the world.”

Chief Justice Mogoeng Mogoeng yesterday (24 January 2013) concluded the proceedings of the first day of the International Symposium on Corruption, hosted by the Faculty of Law of the University of the Free State (UFS). In his address Justice Mogoeng made no excuses as to the magnitude of the threat corruption presents to South African citizens.

“Urgent action and efficient measures are called for to arrest this scourge, for the sake of our constitutional democracy,” he warned. “Our vibrant constitutional democracy will not and cannot survive in the face of rampant corruption.”

Justice Mogoeng said the spate of civil and labour unrest erupting throughout the country can be attributed to corruption. According to him the scope and far-reaching implications of corruption drives South Africans to “boiling point” and evokes “anger, frustration and a don’t-care-attitude that often manifests in widespread protest actions” and disrespect for the rule of law.

“South Africans, irrespective of race or creed, must identify and focus on their common enemies and find a conciliatory and unifying way of dealing with what divides them, including the lingering prejudices of the past,” Justice Mogoeng urged.

Despite the threat corruption poses, he stressed that all South Africans have a role to play in the fight against corruption and that there are different role players that can become involved in the process. Especially important is the media and faith-based agencies which, according to Justice Mogoeng, can regenerate morals and secure a “national moral code.” The State must further ensure enforcement of anti-corruption measures and preside over the selection of individuals of “solid character” to reside in agencies meant to fight corruption.

He highlighted the need for an unbiased and independent judiciary, one immune to outside influences controlled by powerful forces, as well as personal agendas.

Although Justice Mogoeng believes that the private sector is most guilty of transgressions based on corruption, he stated that a “well-coordinated war” against it must be waged in all sectors in order to stamp it out.

Justice Mogoeng presided over the unveiling of the redesigned foyer of the CR Swart Building and praised the Faculty of Law for its innovation with regard to the symposium.

“I look forward with great optimism to more well-organised symposiums that strike at the nerve-centre of the well-being of our constitutional democracy,” he concluded.

Symposium seeks answers and solutions

The Faculty of Law at the University of the Free State (UFS) concluded its International Symposium on Corruption on Friday 25 January 2013. The event featured a stellar cast of speakers, including the Chief Justice of South Africa, three current Supreme Court of Appeal judges, high-court judges, advocates, prosecutors, journalists, as well as local and international legal academics.

Throughout the two-day symposium, corruption was dissected as a severe problem in the South African socio-economic landscape and solutions were sought to alleviate the pressing concern.

The main attractions of the symposium were undoubtedly the attendance and presentations delivered by Chief Justice Mogoeng Mogoeng, as well as Prof. Leon Wessels. Prof. Wessels was described as “one of the founding fathers of the constitution of South Africa” by Judge Fritz Brand, a current Appeal Court judge and the third-longest serving judge in the country.

“Corruption is stealing the constitutional dream of this country. Corrupt leaders are fearless, those who expose corruption, are fearful,” Prof. Wessels warned.

Judge Brand closely trails the second longest serving judge in the country in former Kovsie, as well as former UFS Council Chairman, Judge Faan Hancke. Both judges addressed the symposium and chaired sessions, along with Prof. Johan Henning, Dean of the Faculty of Law, and Judge Ian van der Merwe, Chairman of the UFS Council.

It was, however, not all doom and gloom, as several of the speakers offered tangible ideas in what was often termed the “war on corruption”. Celebrated Sunday Times journalist Mzilikazi wa Afrika who has been arrested following the police leasing scandal which he exposed, urged South Africans to stand together in their fight against corruption, before it is too late.

People on the front lines in the day to day fight against corruption also spoke at the symposium, giving the audience a better understanding of the intricacies and challenges involved in the process. The Head of the National Prosecuting Authority’s Asset Forfeiture Unit, Mr Willie Hofmeyer, as well as Advocate Xolisile Khanyile, who is the Director of Public Prosecutions in the Free State, elucidated this struggle.

The symposium also hosted Prof. Chizu Makajima, a celebrated academic from the United Kingdom.

The two-day symposium ended in style as the delegates gathered in the Centenary Hall on the Bloemfontein Campus for lunch, with a further address by Prof. Leon Wessels
